Be it known thatl, FRANCIS lV; TUL'LY, citizen of the United States of 'i/meriea, and resident of Brookline, in the county of Norfolk and State ot ll/lassachusetts, have in* Vented new and useful Improvements in lindowCleaning Apparatus, of which the following'is a specification.
My invention relates to apparatus for cleaning windows and the like, and has for its objects, amongother things, the provision of portable and'easily manipulated means for cleaning surfaces such as .those oli windows, rapidly and safely,l and with aminimuni ot' cleaning; liquid; the provision also of means for absorbing from the cleaned surface the cleaning liquid and dirt collected thereby in the shortest possible time after said liquid has performed its cleaning- 'function. A variety of useful results are obtainable by the employment of apparatus embodying' my invention, according,` to the situation'in and the conditions under, which, it is used. Theoutside surfaces ofwindows can be cleansed by means of this apparatus without obliging the operator to sity or stand on. the window ledge outside; in cold weather my improved cleaning apparatus absorbs and removesthe cleansing liquid before it has had time to freeze. Because of the fact that this apparatus employs the minimum Aamount of liquid necessary to ef- 'l'ect gleamingV of the window, or similar surface, it can be usedrto clean the inner surtacesof glazed show cases without removing or disturbing their contents.
Other adaptabilities and utilities otthese improvements will transpire in the course of the following description of an example ot such apparatus.

ripherally disposed posts The stub-shaft 7 is journaleo in the journal portion 2, and flexible driving` means 8, suitably housed in a'tlexible tube 9, connected to the stubshat't 7.
. Fingers l are mounted in the hollow posts 3, and are yieldingly sustained .by springs 5. Each of .the lingers 4 is tipped at 6 with sott material, such as rubber, which is well adapted to make contact with a `window surface. Y
A', tank 10, provided with a suitable lillingbpening 1.0ais keyed orotherwise se cured to the stub-shaft 7, and is thus mounted to rotate on the holder. To this tank thev operating mem'aers of the window cleaner are secured. a drier. The scrubber is adapted to carry water or other cleansing fluid t0, and to Aspread it on, the window surface; the drier is adapted to wipe the lluid from the surface and to absorb and dry it. f
1n the example here illustrated, the scrubber comprises 'duid applying means, preferA ably, the wick 13, supplying fluid to the applying' surface by capillarity, and sustained by the saddle l2 mounted on posts 11, and
housed by the walls 18, and fluid spreading` means, namely; the flexible strips n or squeegees7 19, held between the walls 18 and clamping` plates 20. The squeegees or sprcaders 19 willpreterably be made of rubber; though leather will serve. The drier here shown consists of stripslet of cloth, felt, or chamois-leather, held in assemblage between convoluted metal strips 15, 16.
AThese strips are secured by pivot pins 23 and screws Qi to ears 21 and 22 which project from the clamping' plates 20, and are also steadied by engagement with posts 25 mounted on the side 17 of the tank 10.
The scrubber members,`i. e. wick 13 and spreaders 19 preferably extend'dialnet-rically across the rotary member, i. c., tank lll; while the drier members, i. e., felt or soft absorbent leather strips l/l surround tbe scrubber. By disposing" the drier iu convolutionsn a relatively large quantity of wip ing and al'isorbing.material isproyided.
The clamping plates`20 are secured in position by disengageable means, such as tbe eye-boltsQG and wing-nuts 27. The outer fstrips 16 are pivoted at 23, and'held at the l other ends by screws 24, which pass through the eyes 16. By removing screw 24, the strip 16 can be swung outwardly-" as sug- These comprise a scrub-ber and l sev crested bythe dotted line position of the strip in Fig, -and the drier-material 1l removed to be Washed, or reversed, when necessary.
The operating surfaces of the scrubber and drier are in substantially the same plane, so that when the rotary member (the tank l() in the illustration here shown) is rotated, as by flexible shaft S, the performance of the respective scrubbing, wiping, and drying` functions is sin'iultaneous.
F or facility in handling the above dcscribed apparatus, the handle 29 is provided. This is pivotally secured to the journal e1.:- tension 2 of the holder at 2S, and is steadied by means of the curved arm 3U, which passes through the handle 29 at S3. lSprings 3l and surround the arm 30, and abut, respectively, against the holder 1 and nut 3l. Both these springs normally Xert pressure against the handle. 29, which is thus held in yielding relation to the holder l.
The operation of the above described apparatus is as follows:
The tank l() having been iilled with Water or other cleansing iluid, and the aperture l0 being closed'the person operatingthe apparatus takes it by the handle Q9 and brings the tips 6 of the yielding lingers 4 to bear on the surface to be cleaned, and sets the rotary member-i. e. tank lO, with the operatinpfactors carried thereby into rapid rotation by starting a motor (not shown) which is conveniently attached to the flexible shaft S. The capillary action of the wick 13, which serves as the liquid applying means, draws the cleansing fluid from the tank l0 and deposits it on the surface to be cleaned, Wet-ting` an area swept by the face of the. wick as it rotates. The squecaeestrips 1S) spread the fluid over (he surface, aiding the fluid to start the dirt. The Wipers and driers l-l absorb the liquid and pick up the dirt; thus the wetting, spreading', wiping and drying,l go on simultaneously. The operator traverses the apparatus, over the surface to be cleaned, so that all parts of the surface are subjected to the action of the above described operating factors.
Very little Water or other cleansing' fluid is actually required to remove a film of dust, such as collects on glass surfaces, and an adepiate amount for the purpose is supplied by the capillary action of the liquid supplying means here described. Preferably, only the minimum of fluid required, will be supplied; a surplus, hoivever, will do no harm in most instances. But in very cold Weather, it is desirable to ivipc and dry a Window pane promptly after the application of Water, and to use as little Water as possible, in order to avoid the formation of ice. Also,if show cases and the like are tobe cleaned, the minimum necessary quantity of Water for cleansing purposes can be immediately absorbed by the above described aparatus, which can be used, therefore, without necessitating the removal of articles on exhibition in the. show case. lt is obvious from the foregoing description that the cleaning apparatus can conveniently be employed in places difficult to reach with ordinary appliances. Moreover the abovedescribed apparatus is in large measure selfcleaning. lf, While cleaning' a ivindoiv the holder be removed from the glass, the reduction of load on the motor vill speed up 'the rotation of the tank l0 and the cleaning iustruinents carried by it, and the .vater and dirt Will be centrifugally flung out of the wiper pads 14:.
The principle on which the cleaning` apparatus operates is, as descr`bed in detail above, the simultaneous action of ascrubber and drier in close juxtaposition; this is effected by having the operating faces of these tivo factors in substantially the sameA plane; also, the application and spreading of cleansnie fluid from a center outward to the drier; this is effected bylocating the scrubber inside the drier.
lVhile means for affording a more copious supply of cleansing fluid than the capillary wick might be employed, the capillary wetting means is preferred, since it is economical and supplies enough for eliective Work. The VWick, as arranged in the. appa ratus herein described, itself performs a part of the spreadingl and scrubbingl function, and might be employed Without any auxiliary scrubbers such as the squeegee strips. These, however, are to be recommeiuled, for, not only do they assist materially in spreading the fluid, but they also give the surface a ivet wipe, aud relieve the face 'of the wick from frictioual abrasion.
